What Was with The Dead Birds on 45th and Coulter?

I was driving to my boyfriend's work and noticed there were a bunch of black spots on the ground around 45th and Coulter.

As I got closer I thought to myself, "looks like a shredded up black garbage bag." As I came to the light to my horror I realized they were all birds.

I snapped a quick photo at the red light. I figured maybe they froze on the power lines above or were electrocuted. Some of the birds were flattened by passing cars. Either way, nature can be really brutal.
